Abstract

The utility model relates to an asphaltene extraction element is used in laboratory comprises asphaltene extraction element, heating element, extractant recovery element. The asphaltene extraction component realizes asphaltene extraction through similar compatible principle, and the heating component is responsible for heating for whole device, and extractant recovery component realizes the recovery of extractant. In the asphaltene extraction process, because similar compatible principle realizes the initial separation of asphaltene, because total pressure in the retort is unequal with waste liquid jar total pressure, there is the pressure differential, reduces gas pressure in the waste liquid jar this moment, causes waste liquid and asphaltene residue to separate. In the process of extracting the asphaltene by the extracting agent, because the boiling point of the heating water phase is larger than that of the heated extracting agent, the extracting agent is separated from the asphaltene through evaporation, and the gaseous extracting agent is condensed by the condensing pipe and liquefied again, so that the use cost of the extracting agent when the asphaltene is repeatedly extracted is saved. The device fully considers the laboratory conditions, is simple, occupies small space and has strong economical efficiency.
